HAROLD J. DORRANCE, 0F PITTSBURGH, PENNSYLVANIA.

OSTEOPATI-IIC-TREATMENT TABLE.

To all whom it may concern:

Be it known that I, HAROLD J. DORRANCE, of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Osteopathic-Treatment Tables, of which the following is a specification.

The prime object of my invention is to provide a new and improved table, particularly designed for use by osteopathic practitioners and mechanical therapeutists.

A further object of the present invention is to provide a table of the class described including a fixed table member and a movable table member, the latter being designed to be moved vertically both above and below a horizontal plane, and laterally relatively to the fixed member.

A still further object isto provide simple and eflicient means for supporting the movable table member and imparting thereto the desired movements relatively to the fixed table member.

In the accompanying drawings, which illustrate an application of my invention; Figure 1 is a part elevational View and a part longitudinal sectional view, the section being taken on line II of Fig. 2; Fig. 2 is a top plan; and Fig. 3 is an end view.

As illustrated and as preferred, the table comprises a fixed member 1 supported by straight vertically extending legs 2 and by inclined bent legs 3.

The table construction includes a member designed to be moved vertically relatively to the fixed table member 1, both above and below the horizontal plane of the fixed table member, and to be swung laterally thereof. As shown, this member is designated by the numeral 1, and will hereinafter be referred to as the movable member or the movable table member. Interposed between the said fixed and movable table members, I provide a'hinge construction comprising an angle piece 5 fixedly secured to the table member,

and provided with hinge lugs 6; a movable hinge member or casting 7 the latter being provided with lugs 8 adapted to register with lugs 6 and be connected thereto by a hinge rod 9. The preferred shape of member 7 is particularly shown by Fig. 2 and, as illustrated, it is formed with a curved recessed face 10 and with a curved flange member 11. The movable table member, at its inner end, is curved or rounded as shown at 12, and this curved portion is adapted to Specification of Letters Patent.

Application filed February 7, 1913. Serial No. 746,797.

be entered in the curved recessed face of member 7.

Rigidly secured to and movable with the movable member 7 are supporting means for the movable table member 4:. These supportmg means, as illustrated, comprise a frame or bracket including an annular bearmg member 14, arms 15, and a segmental rack 16. The movable table member 4 is plvotally connected with the supporting means by a pin 17 passed through the bearmg member 14: and a bearing plate 18 carried on the underside of the table member 4. 19 designates rollers interposed between the sand bearing members, and constitute a roller bearing on which the movable table member is mounted. This construction permits the movable table member 1 to be swung laterally on the supporting means and laterally with respect to the fixed table member 1. The positions into which the movable table member may be swung are shown in dotted lines in Fig. 2.

In order to lock the member 4: in any des red position, when swung laterally rela* tively to the member 1, I provide a transversely extending rod 20 operable from either side of the table by means of a lever 21. Rod 20 is provided with a cam 22 adapted to cooperate with a curved bearing 23 secured to the underside of the movable table member 4.

The operable means for moving the movable table member 4: vertically both above and below a horizontal plane include, in addition to the segmental rack 16, an operating shaft 24L having its ends supported by the legs 3. Shaft 24: is provided with hand operating wheels 25 and with a bevel gear 26, the latter being adapted to mesh with a gear 27 carried on an end of a worm shaft 28. The worm 29 of shaft 28 is designed to mesh with a worm wheel 80 mounted on a transversely extending shaft 31, the latter having its ends mounted in bearings 32 secured to the legs 3. Shaft 31 is provided with a centrally disposed spur wheel 33, which spur wheel is adapted to mesh with the segmental rack 16.

From the foregoing, it will be noted that the movable member 1 may be raised and lowered relatively to the fixed member 1 into any desired position either above or be low the horizontal plane of the fixed member of the table, and that the operable mechanism for raising and lowering the said member 4 may be actuated by the hand wheels 25 from either side of the table.

34 designate depending members respectively secured to the underside of the movable member t. These members are provided to enable an operator to swing the member 4 laterally by pressing against said members.

An extension rest 35 is provided at one end of the table, and 36 designates a ver tically movable extension located at the other end of the table. Extension 36 is provided with a curved depending rack member 37 adapted to engage with a cross rod 38.

39 designates adjustable stirrups secured to the sides of the fixed table portion 1.

WVhat I claim is:

1. In a table of the class described, the combination with a fixed member, of a movable member, operable means for supporting and moving the latter member vertically wit-h respect to the fixed member, means pivotally connecting the movable member and the supporting means to. permit a lateral movement of the movable member thereon and relatively to the fixed member, and means for locking the movable member in a laterally extended position.

2. In a table of the class described, the combination with a fixed table member, of a movable table member, supporting means for the movable table member positively operable means cooperating with the supporting means for moving the movable member vertically, a roller bearing for the movable table member, and means pivotally connecting the latter member and the supporting means to permit a lateral movement of the movable table member on the supporting means and relatively to the fixed table member.

3. In a table of the class described, the combination with a fixed table member, of a movable table member, a hinge connection between said members to permit a vertical movement of the movable table relatively to the fixed table member, supporting means for the movable table member, a roller bearing for the movable table member, means pivotally connecting the latter member to the supporting means to permit a lateral movement of the movable table member on its supporting means and relatively to the fixed member, and positively operable means cooperating with the supporting means for raising and lowering the movable table member.

4. In a table of the class described, the combination with a fixed table member, of a movable table member, a hinge connection between the said table members to permit a vertical movement of the movable member relatively to the fixed member, supporting means for the movable member secured to a movable hinge member, and means pivotally connecting the movable table member and its supporting means to permit a lateral movement of the movable table member on said supporting means and relatively to the fixed table member. 7

5. In a table of the class described, the combination with a fixed member, of a movable member, a hinge connection between the said members, means for supporting the movable memberincluding a segmental rack and positively operable means for moving the supporting means to raise and lower the movable member relatively to the fixed member including an operating shaft, and gearing interposed between said shaft and the segmental rack, and means pivotally connecting the movable table member and its supporting means to permit a lateral movement of the movable table member relatively to the fixed table member.

6. In a table of the class described, the combination with a fixed member, of a movable member having .a rounded end portion, a hinge connection between the said members, said hinge connections comprising a movable hinge member having a curved recessed face in which the rounded portion of the movable table member is entered, means for supporting the movable member, means pivotally connecting the movable table member and its supporting means, and operable means for moving the supporting means vertically.

In testimnoy whereof I afiix my signature in presence of two witnesses.

HAROLD J. DORRANGE.
